'WATER-PURIFYING .APAMTU lpplication led December 4t, 1920. Serial No. Ma.

To all whom t may concern:

Be it known that l, HARRY W. Giesen, a citizen of the United States, residing at Wellston, in the county of Jackson and State of Ohio, have invented a new and useful vllVater-Purifying Apparatus, of

' which the following is a specilication.

` llo 'llhe device forming the subject matter of this invention is adapted to be used for purifying water, and one object ol the invention is to provide novel means whereby a chemical may be mixed and mingled with the water. Another object or" the invention is to improve the ilter. A. further object of the invention is to provide novel means lor e'ecting a settling of the water, a slow surface current being permitted whilst the settling operation is going on.

llt is 'within the province ot the disclosure to improve generally and to enhance the utility ot devices ot that type to which the invention appertains.

With the above and other objects'in view, which will appear as the description proceeds, the invention resides in the combination and arrangement ol parts and in the details of construction hereinatter described and claimed, it being understood that, Within the scope oit what is claimed, changes in the precise embodiment oil the invention shown can be made without departing from the spirit of the invention.

ln the accompanying drawings Figure 1 shows in `side elevation, vice constructed in accordance with the invention; Figure 2 is a top plan; Figure 3 is an elevation showing the water wheel and the chemical tank, he tank appearing in section; Figure d 'is a vertical section showing the receiver into which the mechanism depicted in Figure 3 discharges; Figure 5 is a vertical section taken through the tilter, parts being broken away and parts appearinin elevation.

he nature of the device is such that the operation may be set forth along with the a del description ol the structure.

'll`he water to be treated may be derived from any source. ln Figure 2, a pump 1 is employed for drawing the water from a well 2, the water being discharged through a branch 3 into a pipe 4.-. Noting the point at which the reference character 5 isapkplied in Figure 2, it will be obvious that there may be as many branches, pumps and vwells as is considered expedient. The pipe e discharges into an aerator 6 (Figure 1). From the aerator 6, the water hows into the casing of a water wheel 8 which may be 1ocated above a platform 9. rl`he water flows from the casing'of the wheel 8 through a pipe 10 (Figure 3).'

, A mixing tank 11 (Figure 3) is mounted on the plat-form 9 and has an outlet 12 communicating with the pipe 10 which leads from the water wheel 8. A receptacle 28 is supported at 29 on the platorm 9, the water wheel 8 being carried, if desired, by the mixin tank 11, as indicated in Figure 3. The c emical which is to be added to the water, is stored in the receptacle 28 andows into the mixing tank 11, the tlow of the chemical being controlled by a valve 30, shown in Figure 1.

il shaft 1e is journaled inthe tank 11 and carries a beater 15, the shaft and the beater constituting an agitator. 'llhe upper end ot the shaft lll is connected by beveled pinions 16 or in any other desired way, to the shaft 17 ol the water wheel 8. A laterally extending arm 18 is secured to the agitator shaft 14: and is provided at its outer end with an enlargement 19 adapted to cooperate with a lever 20, tulcrumed at 21 on-a bracket 22 extended inwardly from the miaing tank 11. The outer end et the lever 20 is oosely pivoted to a plunger 2li, mounted to reciprocate'v vertically in guides 25 carried by the tank 11. The plunger 2l is supplied at its lower end with a valve 28 adapted to seat in the outlet 12 of the mining tank 11. ln order to secure a prompt seating of the valves 26, the plunger' 24': carries a weight 27..

The pipes 7 and 10 constitute a conduit, wherein is interposed a motor, represented by the water wheel 8. 'lhe water, traversing the ipes 7 and 10 operates the motor or water w eel 8 motion being transmitted to the shaftl 17, the shaft 17 driving the shaft 14e by way oil the beveled pinions 16. 'lhe beater 15 is olperated and edects a thorough mixing ol t e chemical in the tank ll. Each time that the enlargement 19 ot the arm 18 on the shaft le passes the lever 20, the lever is tilted on its ulcrum, 21, the rod 2l being raised, along with the valve 26, the outlet 12 of the tank 11 being opened baffle 33 within the shell and a tubular inner 34. 'The baille 34 momentarily. At each rotation of the shaft 14; therefore, a small amount of chemical is delivered through the outlet 12, into the pipe 10 to mix with the water traversing the pipe. The amount of chemical delivered depends upon the speed with which the water wheel 8 is operated, and the speed at which the water wheel is operated, depends upon the amount of water traversing the pipes 7 and 10. The ratio between the water and the chemical is kept practically constant, in view of the construction and the operation above set forth.

The numeral 31 denotes a'receiver (Figure 4) comprising a shell 32, a tubular outer baille 34 within the outer baille 33. The inner baille 34 has a funnel-shaped bottom 35. The pipe 10 enters the receiver 31 and conlmunicates with the bottom 35 of the, baille is of less height than the baille 33. The shell 32 carries a funnelshaped base 36 having .an outlet 37.

.The water and chemical, proceeding from the pipe 10 enters the inner tubular baffle 34, through the bottom 35. The mixture flows upwardly through the baille 34, downwardly between the baffle 34 and the baille 33, upwardly between the baille 33 and the shell 32 and outwardly through a pipe 38 shown in Figures 1 and 2. Owing to the fact that water and the chemical are-comelled to move upwardly and downwardly,

y a sinuous path in the receiver 31, a thorough mixture of the water and the chemical is effected. When it is desired to drain away the sediment in the receiver 31, such a result may be brought about by opening the outlet 37.

The numeral 39 designates a settling tank,

havin any desired number of partitions 40, 41 an 42 extended across the tank and upwardly from the bottom thereof. In one end of the partition 41 there is a notch 43, the partitions 40 and 42 having similar notches, located at those ends of the partitions 40 and42 which are remote from the notch 43. yA wall 44 extends. between the partition 40 and the shell of the' settling tank 39, the wall defining compartments 45 and 46. The pipe 38 communicates with the compartment 45. j

T e' water flowing' from the receiver 31, enters the compartment 45 through thepipe 38 and flows over the wall 44 into thecom- Egrtment 46. The water, thence, passes tween the partitions 40 and 41, through the notch in t e partition 40, the-water flowlng into the space between the partitions 41 and 42, through the notch 43, the water'passing into the compartment 47 between the partition 42 and the shell of the tank,

through the notch in the partitioh 42. The

flow of the water is arrested in the settling tank 39, but there 1s :eslow surface current,

63 (see Figs. 2 and back. and forth, between the partitions 40, 41l and'42. The sediment sinks to the bottom of the settling tank 39 and may be drawn ofi into a sink 49, through a pipe 48 under` the control of a valve 50.-

From the compartment 47 of the settling tank 39, the water flows through a pipe 51 to a settlin tank 52 having partitions 53 constructedike the partitions 45, 46 and 47 of the settling ltank 39. The operation of the settling tank 52 is the same as that of the settling tank 39, and there desired number of settlin tanks. ment in the settling tan throu h a branch 54 into brano having a valve 55.

The water, flowing in a surface current through the settling tank 52, passes from the last compartment 56 of the settling tank into a pipe 57 provided with a valve60. The pipe 57 has a depending end 59 (Figure 5) discharging into a filter 58.

The filter 58 comprises a box-like body 61 which may be` reinforced by tie rods 62 (Figure 2). In the bottom of the body `61 is located a filter bed 63, which may be made of any desired material. The end 59 of the pipe 57 is provided with internal lugs 64, wherein a stem65 is slidable for adjustment. Set screws 66 or'other clamping devices are carried by the lugs 64 and engage the stem 65. The numeral 67 marks a spreader of conical form, interposed between the end 59 of the pipe 57 and the filter bed 63. At its lower end, the spreader 67 is supplied with an annular flange 69, projecting upwardl away from the filter bed 63. The

may be any The sedisprea er 67 is threaded at 68 on the stem 65. i

The water flowing from the end 59 of the pipe 57 is received by the spreader 67 and is diverted laterally toward the sides of the body 61 of the filter, the water thus being distributed over the filter bed 63. The downwardly flowing water is .received by the flange 67 ahd is diverted upwardly, away from the filter bed 63. As a result, the filter is not scoured out belowand adjacent to the spreader 67. The wa in which the water is spread by the member 67 depends to 'some extent on thev positionl which the member 67 occupies with respect to the end 59 of the pipe 57. An approximate vertical adjustmenet of the spreader 67 may? be brought about by slidin the stem 65 in the lugs 64, the stem being eld in adjusted position by the clamping elements 66. A finer adjustment may be secured by rotating the spreader 67 on the stem 65, it being recalled that the spreader is threaded at 68 to the stem.

A header 70 is located in the filter bed i 5) and is provided with lateral branches 72 having perforations 73, the header being closed at one end as indicated at 71. A pipe 74 leads4 from the headmesnil'.

er 70 and is supplied with a valve 78, the pipe discharging into a well 75 communicating with a tank 76. The numeral 79 denotes a main havingv a valve 80. The water may flow directly from the tank 76 into the main 79, or it may be discharged into the main, through the instrumentality of a e pump 77.

linterposed in the 'the branches 72, the water leaving .the impulse of the ln order to :divert The water passes downwardly through the filterbed 63 and enters the header 70 through by way of thepipes 74 and flowing into the well 75. The water finds its way into the tank 76, and leaves through the main 79, through pump 77 or otherwise.

A `pipe 81 is branched od from the pipe 74 and leads to a sewer 82, a valve 83 being pipe 81. The valve 78 ma be closed, andthe valve 83 may be opene the water from the well 75, and for the further purpose of permiting the operator to observe the condition of the filtered water, at anytime.

A pipe 84 is branched od from the pipe 79 and is under the control of a valve 87, the pipe 84 being connected to one end of the header 70. A pipe 85 leadsfrom the pipe 77 to a source 86 of water supply.

The pump 77 may be used to draw water through the pipe 85, the valve 80 being closed, and the valve 87 being open. Under such circumstances the water may be discharged throught e pipe 79 and through the pipe 84 into the header 70, the water traversing the lateral branches 72 of the header 70 and being forced upwardlyv through the filter bed 63, for the purpose of washing away the impurities which may rhave collected in the filter bed.

After a washing of the sort above alluded to, or at any other time, the impurities on the top of the filter bed 63' may be drawn 0H through the instrumentality of a mechanism which will now be described.

A pipe 88 communicates with the sink 49., one end 89 of the pipe upstanding 'within the'body 61 of the'iilter, as shown in Figure 5 the end 89 ofthe pipe being supported on a strut 90 and carrying a nipple 91 surrounded at its upper end by and supporting .a collar 92 which extends upwardly to the surface of the filter bed63. A. guide 93 is mounted on the body 61 of the filter 58, a

tubular gate 94 being mounted to reciprocate in the guide. rlhe lower end of the gate 94 is received slidably-within the collar 92 and seats on the upper end of the nipple 91. A bearing 95 is located in the gate 94 adjacent to the upper end thereof, ,the gate being provided near its lower end with an internal bearing 96. A shaft 97 is mounted to rotate in the bearings 95 and 96. Collars 98on the shaft 97 cooperate with the bearing 95 to prevent the shaft 97 from moving lengthwise with respect to the gate 94. The

shaft 97 is threaded at 99 into a bracket 100 carried by the body 61gof the filter 58, the shaft carrying at its upper end, a hand wheel 101 is above the upper end of the collar 92, and thenA the sediment on the filter bed 63 will bewashed away through the collar 92, the nipple 91 and the pipe 88 into the sink 49.

The operation of the device has been set forth hereinbefore, in .connection with the various component mechanisms, and, therefore, a brief resum of the operation will suffice at this point.

rlhe chemical is mixed in the tank 11 by the agitator ifi- 15, the agitator being driven from the wheel 8, through which the Water passes. ,The chemical is delivered into the Water at the outlet 12 of Figure 3. The Water and the chemical enters the receiver 31 and are mixed therein. From the receiver 31, the water Hows in a slow surface current, across and through the settling tanks 39 and 52, the water entering the filter 58 over the spreader 67. Having traversed Athe filter bed 63, the filtered water is selected by theheader 7 0 and its branches 72 and is what chemical tank; means for driving the agitator from the motor; and

means under the control of the agitator for governing the flow from the tank into the conduit.
